Be il: known than' l, Il iurnr Lonnie, u citizen of lli United Stilles. und i 'resident oi' the 'city zuid county of Denver, in lho Smic oi' Colorado, leinj'ioruril-r residingr et New York, in the county of Non )fork :ind Hielo oi New York, have invented provements in (.foinbina ion`l.iorks, oi' which the following is a specification.

My invention relelios look having apluralitv of bolts in. i'he forni ol' disks which are free to revolve in either di* reotion and adapted to he rotated into und out of engagement. with e suitable keeper, said bolts requiring opening the lock.

Locksoi" this cha-rector es heretofore ronsiruoted have had the bolts or disks niounied upon e. central support in conter-l with each other or in Contact with the control operating-spindle which is revolved i or lurnini)r the disks, andwhen n disk has been ilu-roby adjusted Lo its proper position it is liable to be moved out of position bv the suwe'eding movements ofthe spindle which are required for adjusting the remaining his being because of i'ricionzil Contact oi" (he disks with each other or with the spindle.

'The mein object oi' my inove'sll liability oi n disk beinzgr inovml from its adjusted position by :mism which inusi be moved i'or wijnsti-ng the remaining disks, and this i' accomplish b v mounting the disk or disks than: aire noi li-' recl'lv coupled to the rot-sting mechanism inch-pandently of said mechanism, so that', necessary mov'einents of ssid mec ninisin will not be communicated to a disk that has been once properly udjusiod. n

The face of the look is provided with eis tensions or flanges d, which project laterally beyond. the sides or beyond the ininnlsrwnll l ofthe easing, said extensioiis being provided with sorewhholes d', by ineens olI which the Alook is secured to the edge oi the door or est dietineter of the disks to the.openingl drawer, the hitter being out out to receive the annuler wall oi the lock, es 'clearly sliown.

F or confining the lower portion of the-'lock in place a' spur g is providedl et the 'under side of the easing, which may be driven into the Wood'or vfitted into a hole provided therefor, as elearlv shown in Fig.

The lookieeper 'l is secured to the easing i of the door ord'rawer in proper position to register with the leek, and the front will l/ of t the -ldckoesing is insdeto extend upwardly beyond the face of the lock, es et. b, to pre- Vent e knifedilade or other device from being inserted between the ieee ol" the loe-k and the kee er for the purpose of moving the bolts.

'vlhe opening in the foce of the loek through ieli the 'bolts or disks are inserted is slightly greater than ,snnillest diameter of the disks, so that the latter een onli7 be insorted inthe easing by presenting the smell- *indicated in dotted lines in Fig.

at its opper edge seid plete is provided with n.

slotted flange if, which completely covers' the fece of 'the look at all points not reqnired to be open for the proper movements ol the rotating bolts. I)

As iilreridy explained, the disk or bolt A is rotatively eouplezi to the spindle E, 'So that when the latter is revolved the diskA is also revolved. Said disk or bolt A .is rovided with n projection or pin i., which is in ine with ve. pin 'i' on the 4disk A, and the httteifis provided with :inet-her pin i2 in iine 'with s pin i By turning thospindle E that the pin 'i on the disk A engages with the pin i on thodisk A the letter may he revolved for cousiner its pin i? to move the disk A2 bvfeontnet with the pin i. may be 4thus sdjusted'to itsproper position foropening the look, und b v rwversiiig` the. direetion of rotation of the spin'ile the disk A may be properly adjusted without liability o'li disturbing the adjustment of the disk A. When these two disks have been adjusted, the directionl ol: jrotntion ol the spindle is again reversed l'or .-izijusting the disk 'A'. When all three disks hzive been adjusted in line with each other :ind `with their straight edges rt in line 'with the l'nee ol" the lof-k` seid The disk disks will be tree from the keeper (Lend the drawer or door nniy be opened. Yhen the door or drawer is rinsed, two or three turns oi the spindle l?) will throw the disks or bolts out ol line uwith ene-h other :ind in engage- 1 nient with the keeper, :is will be readily understood.

The nioveinents of the spindle [or ope/ning the ioek nr :supposed t'o be known only to the persons iiutl'iorized to open the seme, end said movements are guided by the numbers on the dial A'F in weli-knrm'n rna'nnerl When it is desired to change the combination, the nut e2 ispsrtiell)v withdrawn or nnsereived from the spindle if', ind the letter is polled slightly out ol' the loek-ensingA ind turned so that the relzttive positions of the disk A 'and spindle E nitty he f shengeiii by shitting; the pin or pins e l'roui one notch .2 to si'iother, as will be u'n derstood, the spindle being pushed beek in /the desiree position. `end the nut e? again tightened. The required movements of the spindie vi'or openingr the look 1will then be .Gow erned. by numbers on the diri-l F, didi-ring trom the numbers of the originel combina? tion..

For preventing the nut e from becoming det-ziohed 'from 'the spindlel there. is a screw if tapped into the resi' end of the spindle,

with e. shonider on the interior of the nut e2. This screw .it is withdrawn from the spindle sufficiently to permit thev nut e2 to be VWithdrown the require-:i distant-.e lfor changing the unlocking' minbination wl n desired, the ist ter operation heine; readily performed with'N ont opening; the lock-ossing or disturbing en v oi'its parts.

It is to'l'ie, noted that the bolts or disks A and A2 fire Wholly supported by the looleoosingend tlnitthey :ire not in any nnniner oonneoted with the operetingsspindle except through the medium of the projecting pins which :tre provided for transmitting motion from one disk to eiiotl'ier, :tud when ssidpins are not in eingog'eunint .with erich other the disks A sind A2 sonnet be moved. This is :in importa-nt und velnitble ifea-ture oil in v invention, :is it removes all liability of an adjusted disk beingpdisturhed by subse nent movements of the operritingepindle W irfh may be necessary for odjnstii'ig;r otherdisks'. f
